The DBH 9257 radial shaft seal is a lip seal designed to be mounted on a 24.5 mm shaft and housed in a cavity with a height of 10.50 mm. Its function is to retain lubricant inside the assembly and prevent the ingress of dust, water or contaminating particles. It is used in gearboxes, pumps, electric motors and power transmission equipment. MR Accesorios Industriales carries this brand and advises you so you choose the correct seal for your application.

This item is a radial shaft seal from the DBH line, identified with the part number 9257. According to the product page data, it corresponds to a shaft of 24.5 mm diameter and a total height of 10.50 mm. The A 181 design defines the geometry of the lip and the metal case, although the housing diameter is listed as 0 mm, so that data is confirmed against the manufacturer's technical data sheet before quoting. It is a single lip seal, with spring, suitable for rotating shafts.

Typical applications of this seal include gearboxes, centrifugal pumps, electric motors, compressors and transmission equipment. In all cases, its function is twofold: retain the oil or grease and exclude external contaminants. As it is a wear part, it is advisable to replace it when leaks appear or when the lip shows hardening, cuts or loss of elasticity. It is also used in equipment where axial space is limited and a compact seal is required.

To install this seal, verify that the shaft has the indicated dimension and that the contact surface is polished and free of burrs. Lubricate the lip with the same grease or oil as the equipment before inserting it. The 10.50 mm height must match the depth of the housing. If the housing is damaged, evaluate the use of a seal with a sleeve or an alternative size. Correct alignment between shaft and cavity prevents premature leaks and extends the service life of the seal.
